" a "rotor ot--noveLcontLtlfllQLi This invention relates more particularly to the construction of the rotor of fluid actuated turbines, especially such as are used in turbines of the Terry type where the mouth of the bucket opens at the periphery of the rotor.

The object ,of the invention is to produce .Referring to the drawingsFigure 1 is irsid'eviewwof part of the rotor with on? side plate removed showing some of the buckets in central section and others in side elevation. Fig. 2 is a sectional View on the line 2, 2 of Fig. 1. Fig. 3 is a detail sec tional view of the side plates and base ring on the line 3, 3 of Fig. 1. Fig. 4 is a top view of one of the buckets.

Rotors made in accordance with my invention'comprise a base ring a having a central circumferential groove 5 which is preferably of dove-tail form as indicated in Fig. 2, buckets having tangs (Z adapted to fit in the groove 6, spacing blocks 6 to space the buckets one from another, and side plates 7', f circulnferentially grooved on their opposing surfaces near their outer edges as indicated at g g to receive the side ribs h 72. on the buckets. Bolts i pass through the base ring and side plates, their ends being riveted over to tie the structure together.

ranged in step formationabout the periphery of the rotor and the structure is assembled by sliding the buckets into place on the spacing them apart by the spacing blocks, then fitting the side plates so that the grooves g 9 receive the ribs h h and finally in tying the structure together with the bolts '2'.

There is thus provided a rotor which can be readily and accurately assembled, requiring the least amount of machining Work and producing a strong rigid structure.

I claim as my invention: 1. A rotor comprising a base ring having "5 circumferential groove, buckets provided with tangs adapted to fit said grooves, spac- Tng blocks between said Lapgs, side plates posing surfaces near their p ter edges, ri on said buckets adapted to lie in said grooves, and means for securing the parts together.

2. A rotor comprising a base ring circumferentially grooved, buckets provided-with tangs fittlng in said groove, and side plates between which said ring and buckets are secured.

3. A rotor comprising a base ring circumferentially grooved, buckets provided with tangs fitting in said grooves, side plates between which said ring and buckets are secured, and interengaging parts on said buck ets and side plates.
